Wilson's rallying cry

All eyes were on President Barack Obama entering Wednesday night's address to Congress, but a little-known South Carolina Republican may have done more than the president’s combative speech to unify besieged Democrats around health care reform.

The night's defining moment — which Democrats hope to transform into a turning point — came when Rep. Joe Wilson (R-S.C.) shouted "You lie!" as Obama claimed his plan wouldn't offer free care to illegal immigrants.

Wilson's boorishness — for which he quickly apologized — enraged audience members on both sides of the aisle.

It also overshadowed a speech that included some of Obama's harshest attacks on his GOP critics to date, including a denunciation of "death panel" alarmists as liars — a veiled swipe at former Alaska Gov. Sarah Palin — and a warning to Republicans who want to "kill" reform.

"What we have also seen in these last months is the same partisan spectacle that only hardens the disdain many Americans have toward their own government," Obama said. "Too many have used this as an opportunity to score short-term political points, even if it robs the country of our opportunity to solve a long-term challenge. And out of this blizzard of charges and counter-charges, confusion has reigned.

"Well, the time for bickering is over. The time for games has passed," he added, to Democratic cheers.

The president's combativeness, coupled with Wilson's behavior, clearly energized Democrats — to the point where few were in a mood to criticize Obama's lack of specifics or the fact that he offered no ironclad commitment to inserting a robust public option in the final legislation.

Sen. Ben Nelson (D-Neb.), one of the upper-chamber Democrats most skeptical of the White House reform efforts, was impressed by Obama’s speech.

"I think it was a bit of a game-changer," he said.

"The speech galvanized support along the Democratic Caucus across the political spectrum, from the progressive caucus to the Blue Dogs, and everybody left determined to get something done this year," Rep. Chris Van Hollen (D-Md.), head of the Democratic Congressional Campaign Committee, told POLITICO on Wednesday night.

Republicans — some of whom expressed open contempt for Obama by scanning their BlackBerrys or holding up copies of GOP bills during the speech — saw the president’s remarks as a Democratic call to arms that belied the president’s oft-repeated calls for bipartisanship.

"I was incredibly disappointed in the tone of his speech,” said Sen. Lindsey Graham (R-S.C.).”At times, I found his tone to be overly combative and believe he behaved in a manner beneath the dignity of the office. I fear his speech tonight has made it more difficult — not less — to find common ground.

"He appeared to be angry at his critics and disappointed the American people were not buying the proposals he has been selling. ... If the Obama administration and congressional Democrats go down this path and push a bill on the American people they do not want, it could be the beginning of the end of the Obama presidency."

Rep. Mark Kirk (R-Ill.), who is running for Obama's old Senate seat, said, "He talked at us. He didn't listen to us ... It was a missed opportunity."
